I respectively disagree. The 802.1AVB task force and the AVnu Alliance are agressively targeting automotive infotainment networking. I first proposed AVB as the next-generation replacement for MOST in June of 2006 and Harman publicly showed an automotive AVB demonstration system at the QNX Automotive Summit in Stuttgart earlier this year.

I have heard MOST for at least 5 years, but not sure its popularity now. Any figure?

First off, this article is one-sided & too commercial, peddling SMSC's products, most of which are several generations behind. I do not know what they cost, but if one is looking for ruggedized or harsh environment equivalents of ethernet NIC controllers with PHY's, there are plenty of choices available, even in 1000mb/s data rate (as opposed to 10/100mb/s by SMSC). The IEEE AVB task force 802.1 which has been functioning since 2008 probably never looked into automobile applications as one of the possible use cases. It has also steered clear of the physical medium dependent (PMD) definitions. Ethernet over USB is available today and should be looked at as one of the alternatives to the good old RJ45.

Driver assistance information is one sort of valid reason for expanding connectivity in a car, but I see a lot of much worse uses, such as a driver working on a Powerpoint presentation at 70 MPH, and all kinds of distracting multimeadia tugging at the drivers concentration. Chanj was certainly correct in stating that distraction will cause problems. With todays youth afflicted with the millisecond attention span, these systems may provide the cure for excessive population. Not the preferred method, but effective.

Here's an idea. What if you had a little device about the size of you pocket that you could plug into your car. It would have any music, audio books, or video or possibly even be able to receive video over the air. We could call it a PDA (personal device for audio-visual stuff)

New EthernetAVB-capable SoC's targeted for AEC-Q100 automotive qualification are being announced on a weekly basis. Ethernet is already the world's most ubiquitous networking solution and with the advent of AVB, it now has the guaranteed QoS and low latency needed for realtime multimedia. There's an undeniable cost advantage to AVB infotainment networks - especially when combined with driver assist video - that makes this technology unstoppable. It's my educated guess that we'll see AVB-enabled cars rolling off the line in 2014.

Driving a car requires a lot of focus and attention. As more information is feeding to the driver and the passengers, distraction is inevitable. I wonder who is going to take the responsibility if accident happens - the infotainment provider, the equipments or the driver? I guess this is probably the reason automotive industry will go slow in adopting technology other than those in the core of a car. However, I don't think it is a bad idea to feed information to the driver such as location information, environment such as the closest restaurant, gas station and motel/ hotel. What would be more useful is cars nearby! Connectivity is crucial to the adaptation. The interconnection must be able to resist interference generated by the car as well as minimize interference to the electronic that helps driving the car.

Intead of texting while driving, using a head up display, people can try making the presentation while driving. :-)

This is a very interesting article. As we think of using USB and other devices with Automotive Information Systems, we need to think of security. How are we going to protect these items? This sould like TCP/IP…great idea, now what about security?

I think usb will be best option for in car connectivity for all the peripherals, may be it will require some advancement in the usb protocol but that will be best possible technology to use.
